Likelihood data for selected models.

The optimal model of each type is given in each case. Model codes are : Constant selection at a single locus; : Time-dependent selection at a single locus; : Additive selection at two loci; : Epistatic selection at two loci (where the fitnesses of the and haplotypes at loci and are and respectively, the fitness of the haplotype is ); : Additive selection at three loci; : Additive selection at two loci, second locus time-dependent; : Additive selection at three loci, one time-dependent; : Additive selection at three loci, two time-dependent. Selection coefficients are given in units of . Starred selection coefficients are approximate and could not be determined to high accuracy. The BIC values for the optimal model in each case is displayed in bold. BIC scores are rounded to one decimal place.
